Water is the most basic building block of life. Clean water is essential for human health, wildlife, and a balanced environment. Yet, water is being polluted at unprecedented rates, with pesticides, industrial chemicals, nutrients, metals, and other contaminants. Studies of major rivers and streams find that 90% of fish, 100% of surface water samples, and 33% of major aquifers contain one or more pesticides at detectable levels. As a result of pesticide contamination of streams, rivers, lakes, and underground water supplies, drinking water is also widely contaminated. Although individual precautionary measures provide a short-term solution, with a crisis in safety looming, steps can and must be taken to curtail pesticide use and adopt alternative practices and products to protect the nation's waterways.

According to Beyond Pesticides’ Eating with a Conscience database, more than 50 pesticides are known surface or groundwater contaminants, according to data from the U.S. Geological Survey (USGS) or Environmental Protection Agency (EPA).

According to USGS, 56% of streams sampled had one or more pesticides in water that exceeded at least one aquatic-life federal standard. Many of these pesticides are also linked to a range of human and environmental health effects, including cancer, birth defects, and neurological and reproductive health impacts.

It is essential that these pesticide contaminants not invade our waterways and drinking water. Unfortunately, improper oversight and lax enforcement mean that many of these pesticides do, in fact, continue to contaminate our environment.

Organic agriculture and its food production constitute a system that rejects the use of hazardous synthetic chemicals in the growing, handling, and certification of food. It is the only food production system that is subject to independent public review and oversight, assuring consumers that toxic, synthetic pesticides do not contaminate surface and ground waters. In fact, organic farming reduces or eliminates water pollution and helps conserve water and soil on the farm. According to the Food and Agriculture Organization, several countries in Europe compel or subsidize organic farmers to use organic techniques specifically to combat water pollution problems.

Reduces NutrientRunoff

Organic standards stipulate that soil fertility and crop nutrients can be managed through tillage and other cultivation practices such as crop rotation, which preserves and maintains the fertility of the soil so that synthetic inputs become unnecessary. Organic eliminates the need for and use of synthetic nitrogen/phosphorus-based fertilizers, thereby significantly reducing the threats of nitrogen and phosphorus runoff to aquatic ecosystems, and reduces the prevalence of algal blooms and eutrophication.

Prohibits the Use of Sewage Sludge/Biosolids

Organic does not allow, as a fertilizer, the use of sewage sludge, which is often contaminated with a host of chemicals including heavy metals, pharmaceuticals, and pesticides, which can all re-enter the aquatic environment once the sludge is recycled on land.
